• Repeat the first five steps from the above "Auger

Belt" sub-section to split the snow thrower.

• Pull the idler pulley away from the backside of the

extension spring from the belt cover plate). See

• Roll the drive belt off the lower drive pulley and

remove the belt from the engine pulley.

• Install the new belt on the pulleys in the reverse

order and re-tension with the idler pulley.

washers removed earlier.

• Slip the auger control belt over engine pulley.

Changing Friction Wheel

The friction wheel is subject to wear and should be

checked after the first 25 hours of operation, and

periodically thereafter. Replace the friction wheel if any

signs of wear or cracking are found.

• Drain the gasoline from the snow thrower, or place

a piece of plastic under the gas cap.

• Tip the snow thrower up and forward, so that it rests

on the housing.

• Remove the six screws from the frame cover

underneath the snow thrower.

• Remove the right wheel(s) from the axle.

• Using a 3/4” wrench to hold the hex shaft, loosen

but do not fully remove the hex screw from the left

side of the frame. See Figure 23.

Figure 23

• Gently tap the head of the hex screw to drive the

bearing on the right end of the hex shaft out of the

frame housing; then remove the hex screw and

belleville washer.

• Carefully pull the hex shaft out from the right side of

the frame to slide the spacer and sprocket from the

left end of the hex shaft. The sprocket should

remain hanging lose in the chain. See Figure 24.

• After noting where the pin of the shift arm assembly

is inserted into the friction wheel assemble, hold the
